Import Multi-Entity Builder
Creates relationships between people, records, or conditions without losing context for files, schemas, mappings, and staged imports; it is designed to preview what will be accepted, transformed, ignored, or rejected. Search, selection, ordering, and removal expose counts and duplicate prevention. The import and mapping inputs variant is specialized for large or malformed input must fail safely without losing mappings. Users can preview what will be accepted, transformed, ignored, or rejected while understanding the current state, available choices, and resulting consequence.

Implementation field notes
Use import multi-entity builder confidently.
The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.
Accessibility contract
- The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
- Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
- Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.
Integration plan
- Copy the standalone HTML and scoped CSS into an isolated page.
- Adapt input signal, interpretation highlight, input surface, primary text through the Inspector.
- Connect the defensive JavaScript, then test every control with a keyboard.
- Review the result at 375, 768, 1024, and 1440 pixels before shipping.
